To' all whom/it may conce-mz;

I l Be it known that I, GEORGE MERLE, Jr., a citizen of theUnited States, and residing at Maspeth, L. I., in the county of Queens and State of New York, have inventedcertain new and useful Improvements 1n Multicolor Incrusting on Stones, of which the following is a specification, such as will enable those skilled in the art'to which it.

appertains to make and use the same. I

, This invention relates to the incrustlng of stones of various kinds and classes, such for example as sapphires, rubies,v black onyx and similar precious or semi-precious stones,

and the object of'the invention consists in incrusting stones of the class specified in metals of different color whereby color effects may be produced on the stones in the reproduction of characters, objects or things; and with this and other objects in view the invention consistsv in an article of manufacture of the class specified, constructed as hereinafter described and claimed. i,

The invention is fully disclosed in the following specification, of which the accompanying drawingforms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is'a plan view of a stone with in crustings thereon showing the stone mounted in a ring or other setting; and,

Fig. 2 is a section on the line 22 of Fig. v

In the accompanying drawing I have shown for the purpose of illustrating one use of my invention, a stone 5 such for ex ample as a black onyx which for illustrative purposes is mounted in a ring setting 6, and on the outer face of the stone 5 is arranged incrusting to represent a flower, such for example as a daisy the petals 7 of which are reproduced from aluminum in- .8 and stem 9 of the flower is reproduced in gold incrustings.

In the foregoing it will be apparent that the daisy will be reproduced on the black stone 5, silvery petals representing white petals of a daisy, and the gold stem and pollen representing a contrasting color which will set off the flower to produce a very pleasing and beautiful effect Y Heretofore it has been a common practiceto incruststones of various kinds and classes to reproduce thereon designs of characters, objects or things but, inuthe f present procedure it has-been customary to reproduce such designs all in one color on;

a single stone, that is to say, all aluminum vincrusting would be employed or all gold incrusting, and the object-of my inventioni consists in arranging on 'a I single stone, metals of two or more contrasting colors to bringout more pleasing and naturalef fects in the incrusting work to be applied ;to thestone. I j 1 The lncrustin'g maybe done in accord= ance with either the acid or the engraving process, and in the latter method of procedure the stone is first engraved by a suitable tool to cut in the surface of the stone the desired design or artistic reproduction, which may be a character, ob ect or thing,

after which twenty-four, karat solid gold rolledvery thin and aluminum also rolled very'th-in is pressed in the engravings where l the different metals are required to brin out the desired artistic production, "aftei' which the projections of the gold'and aluminum that extend above the top face ofthe stone may be filed down "flush with the stone surface and, if desired, themetal pressed into the engravings may-be configurated or cut to brmgout other artistic effects.

In the other method of procedure which I is preferably used in connection with the softer stone, the stone is first placed in a cover or jacket of tinfoil which snugly fits the periphery of the stone and entirely encloses it, after which a stencil is placed upon is the top face of the stone and the tin foil around the stencil "is cut by a suitable tool to remove portions of the tin foil in reproducing the stencil thereon, after which a number of the stones thus formed are placed Im a tray or bath with the top stenciled crustings in the stone 5, while the pollenf etch or form recesses in the stone corresponding to the stencil on the tin foil and the stones removed from the tray and also from fthe'tin foil the etchings are undercut by a suitable tool and the above procedure ofv placing the thin gold and thin aluminum 3 'in the grooves or recesses of; the stone is I perfoni-ned. The undercutting of the Walls serves to prevent the accidental displacement of the incrusted metal as Will be apparent.

It will be understoodthat While I have shown" the reproduction: of a daisy on the face of a black onyx, my lnvention l-S not limited in this respect as emblems; shields;

other floral designs and the; like may" be reproduced on any kind or class of stones or st-clnes of any 'shape on \vl'ndh incrusti-ng Work can bedone. i It Will also be understood that flowers or other objects may be jmer'ely outlined on th'estone and the color of the stone itself used as a background or color for the flower or object to be repro- "duced, as Tor example in reproducing a red rose on a ruby, the outline of the rose may need be incrusted in one metal, such for 7 example as aluminum, a'nd'thestem and other portions of the' flower' may be reproduced in the goid; and While I have sho'Wir and described certain details of construction for carrying my invention into eftec'tyit will be "understood that I am not necessarily limited in these respects and various changes in and modifications of the constr'nc'tion :o-t suchsstrr uctuire I-as to retain lustre When subjected to the elements, and sheet gold of a color contrasting to that'oit thealuminum in predetermined "arrangement in the production of a predetermined design on said stone. I i p i' A stone in which is incruste'd combination oi precious and-non-precious metals of contrasting colors, the non-precious metal being of a Whiteor silvery color and of such structure as to retain its lustre When subjectedto the elements;

In testimony that I claim the 'fo-regoing as my invention-I- have' si gned my name this 28th day of Feb'.'1925.
